To solve this problem you must apply the fomrula for calculate the area of a cylinder, which is shown below:
A=2πrh+2πr^2
Where r is the radius and h is the height of the cylinder
You have that r=15.1 inches and h=12.8 inches, then:
A=2πrh+2r^2
A=2π(15.1 in)(12.8 in)+2π(15.1 in)^2
A=2647 in^2
The answer is 2647 in^2

What is the measure of arc BD?

posledela

Since there is no specific situation or measurements for this, we just assume a circle with an arc BD. It has arbitrary values. In a circle, an arc can be measured by the measure of an arc. A measure of an arc is an angle that an arc makes at the center of a circle which it is a part. It has degrees units. It can be calculated when the length of an arc is given by using certain equations. The measure of an arc and the length of an arc always goes together.

Answer: -1 7/8

Turn 3 5/8 into an Improper Fraction

Multiply 3*8 and get 24. Now add 15 and get 39 (Denominator stays the same). 3 5/8 = 39/8

Turn 5 4/8 into an Improper Fraction

Multiply 5*8 and get 40. Now add 4 and get 44 (Denominator stays the same). 5 4/8 = 44/8

Subtract

39/8 - 44/8 = -15/8

Turn -15/8 into a Mixed Number
